The urine and blood test are the most common types of pregnancy tests. These tests help to determine the presence of hCG hormone in urine and blood respectively. In the quantitative test, doctors follow venipuncture process. The venipuncture process involves drawing blood from the veins. The blood test is a sensitive way to detect pregnancy and it also brings more information than a home urine test.
Kinds of pregnancy test: There are two kinds of tests, one is qualitative and other is quantitative. Qualitative test brings a clear cut answer whether a woman is pregnant or not. In the quantitative test, the doctor gives a positive or negative result and provides a measurement that is comparable to the level of hCG as the hCG level nearly doubles about every two days in early pregnancy.
Multiple blood tests help to track the hCG and get better results of pregnancy. It helps the practitioner in monitoring the possibility of miscarriage or ectopic pregnancy. It also tells about the chances of you carrying multiples.
When to undergo these test: Not everyone can afford the stress and expenses these pregnancy blood tests bring along. Consult a doctor before you undertake a pregnancy test.
Quantitative pregnancy test shows the rise in hCG levels during the first trimester of pregnancy. Any abnormality like having twins or triplets, infection or malignant tumours of the uterus causes a decline in the hCG level. They can also identify if there are non-cancerous tumours present in the uterus. Ovarian cancer, testicular cancer (in men) may found there as an abnormal pregnancy.
The lower level of hormones indicates the possible death of the foetus, miscarriage, and an ectopic pregnancy.
There is a very little risk in taking blood pregnancy test. Doctors should be cautious about excessive bleeding, fainting, or infection while drawing the blood.
